I f you are looking for an uber quiet vaporizer that has literally no weed smell then you should get a Volcano Vaporizer. There is no vaporizer like this one! It actually fills a bag up with the sweet sweet Vapor and the bag can be carried around and passed with ease. Take just one of these bags down to your face and you will be stoned for hours on end. The Volcano is the Vaporizer that is Found in all of the MMJ dispenseries because it enables one to taste and differentiate betweeen different strains of bud. I vaped with the Volcano this whole past summer just upstairs from my parents room. They never could smell a thing! When little brothers storm in the room they couldn't smell anything! I am selling mine on Ebay at the moment. I have had it for about 6 months, but i must sell it to pay for my move out to California. MMJ Card Here I Come!
